Point, line and plane are the basic concepts in geometry. In the real world, a point moves into a line, a line moves into a plane, and a plane moves into a body, which constitute the kinematic relationship between them. In recent years, with the continuous development and innovation of stage lighting technology, it has brought unprecedented subversive visual feelings to the television audience, the magician's pattern of play, and even shook the audience to the basic cognition of light. This article we will discuss, these light spectacle, in the television language space construction function.
The light source, starting at the point
By tracing the source of light, we can find the end of the ray. The application of point illuminant, basically rely on the change of colorific and lamps and lanterns arrangement means, often give us lively, jumping or the experience of relative tenderness and romance. In the stage space, point light source is widely used as the background element, and it is also the expression mode that is most closely related to the performance subject, digital stage design and video in the TV lens language. Therefore, as a part of the TV picture background, in addition to the icing on the cake with the changes of the large screen material, the most important thing is to deconstruct the vision, express the theme of interpretation, and lay the atmosphere and tone of the scene, which is the primary task of these point lights. Taking the second season of Chinese Music Festival of Guangdong TV as an example, 60 flat LED pixel lights are used in the spatial background. Through color changes, the brightness is weakened and the arrangement of dot matrix is highlighted, which is very cleverly integrated into the whole visual system.
It is worth emphasizing that the use of this background point light source should take full account of the design of stage structure and large screen elements, clarify the primary and secondary roles played by the light, and make each other shine and complement each other.
Thread, a magician's trick
Among the stage modeling changes, the most commonly used is the beam lamp. If the light as a group of actors, then the most dancing, must be the beam of light group. They have an infinite number of permutations and combinations. Compared with point light source, they have more visual impact. Therefore, they are often used as the main body of light show.
Due to the physical property that light travels along a straight line, the arrangement of beam lights often gives people a visual effect of toughness, strength, or atmosphere, and even increases people's perception of the three-dimensional space of the stage.
In addition to beam lamps, there are many other ways to create linear effects. The most common is the use of lasers. Laser show has also developed rapidly in China for 20 years, but due to its thin lines, high cost and relatively simple application effect, it mainly expresses the sense of future science and technology as well as the pursuit of instant visual impact. For example, the effect seen in the scene in the past is like this.But recently another laser effect has been discovered. It's called the laser split-frequency effect, which upends our understanding of light and produces a visual spectacle that is beginning to be experimented with in music shows. The author also tried a bold application in the second season of Guangdong TV's "Songs of Flow" program.
Light, flying across the screen in split-line segments
Through programming, it can even be presented with the effect of visible light waves. In addition to the expression of sense of science and technology, sense of future and sense of speed, romantic and beautiful lighting vocabulary can also be pursued, such as:
Only when the laser is matched with the camera parameters can it be displayed. So only the viewer in front of the screen can experience this wonderful illusion of light and shadow -- broken and curved. These graceful phantom, subvert the light straight, can not cut off the characteristics.
Laser programming has opened new horizons and ideas for us, and new things are still waiting for us to explore and test more. The interesting thing is that magic is a game of light. Excellent lighting designer, also must be a magician.
All sides are covered
During these years' exploration of TV lighting, the biggest feeling is that the lens language has an impact on the lighting effect. If you want to transfer the charm of on-site lighting to the TV audience, you must follow and rely on the lens language. Therefore, the cooperation with the camera and the director is the top priority in the work. Different from the live performance, the visual effect in the lens of the presentation, is the ultimate goal of TV program lighting. This is like a magician performing magic to the audience in front of the camera, the camera does not cooperate, will inevitably wear the same, the lighting effect is also highly dependent on the picture composition. This puts forward higher requirements for the professional ability and spatial imagination of the director and the director. When the light moves in a point or line posture, it is constructed into a surface. The spatial sense of the stage combined with the camera changes in front of the audience.
Body, is the infinite future
There is a tendency in the production of current TV variety shows to strengthen the sense of visual depth. Through the stage space, video materials, deductive formations, etc., more possibilities are provided for the extension and filling of the space. This initial attempt is undoubtedly successful. And the role play that the light faces also ushered in unprecedented challenge. Lighting designers will consider more, more detailed, understand and make full use of scientific and technological products, is the future direction of development. For example, UAV performance has been leading the exploration and attempt of lighting in the high-altitude field. Perhaps one day, scientific and technological progress will finally realize the freedom of artificial light source, which makes designers' infinite expectation.
